giinilar characters of reference refer to similar parts of the machine throughout the several views of the drawings.

The operating parts of the machine are mounted upon a frame 1 The frame is provided with a support 2 upon which the material rests when it is punched in the manner hereinafter described. Said support is provided with. an opening 3 in which rests the die holder The die holder is recessed at to receive the die "4' which is provided with a punch receiving opening 8. The die holder isprovided with a passage 9 with which the punch receiving opening 8 registers and through which the piece of material which is punched out passes from the die. The upper end of the die holder is provided with an inclined flange 10 which engages and rests upon a correspondingly inclined seat 11 at the upper end of the opening 3 in the support. The lower end of the die holder is threaded to receive a nut 12 which engages the under surface of the support The die holder is slit at its upper end at 13 so that said end of the. die-holder may be compressed to grip the die 7 firmly and hold it in position upon turning the nut- 12 and thereby drawing down the. inclined flange 10 oi 'the die holder against its seat 11. A punch 14: is adapted to co act with the die T to punch a hole in the material in which the eyelet is adapted to he set. A set 15 is adapted to engage the eyelet and push it into the hole punched in the material and to set the eyelet in the material. The punch and set are respectively mounted upon a punch plunger 16 and a set plunger 17. The upper end of the punch in an opening in the punch plunger 16 and is secured to the plunger hv a set screul8. Said punch plunger in a guide on the frame 1. The punch plunger and punch are actuated by a cam 21, in cam disk 22 mounted on shaft 23 journaled in the frame 1, and cam lever 25 fulcrumed at 26 upon the frame I. Said lever is connected to said plunger by means of a stud 28 and link 29. The stud is mounted on the punch plunger and projects therefrom through slots 17 and 20 respectively in the set plunger 17 and guide 20, and is connected at its outer end to one end of the link 29, the other end ofwhich is connected to the cam lever 25. The cam lever 25 is provided with a cam roller 25 which engages the cam 21. The set 15 is supportedon the lower cross member 31 of the set plunger 17, resting in an opening-32 in said member, which opening isinclined at its lower end to form a seat 33 against which rests an inclined flange 34 on the set 15. The upper end of the set is threaded to receive a nut 35 which engages the upper face of the cross member 31 and draws the flange 34 against its seat 33 whereby the set is maintained in position on the plunger. The set 15 is provided with an opening 35 through which the punch 14 extends and reciprocates. The set plunger and set are actuated by a cam 40 in cam disk 22 and cam lever 41 which is fulcrumed at 26 upon the frame 1. The cam lever 41 is provided with aroller 41 which engages the cam 40. Said lever is connected to the set plunger by means of link 42 and the adjusting union 43. The adjusting union 43 comprises a screw 44 having a flat sided flange 45, connecting element 46 which is connected to link 42, washer 47, wrench 48 and lock nut 49. The respective ends of the screw 44 are threaded in opposite directions and engage corresponding internal threads 50 and 51 respectively in the upper end of set plunger 17 and in the lower end of connecting element 46. The washer 47 rests upon the upper end of the set plunger and supports the wrench. 48 which is provided with a flat sided opening 52, in which rests the screw flange 45, the sides of which opening are adapted to engage the sides of said flange, when the wrench is turned, and cause the screw to turn. The lock nut 49 is provided with an internal thread 53 which engages an external thread 54 on the lower end of the connecting element 46, by means of which the nut is screwed against or away from the wrench 48. Upon urning the screw 44 by means of the wrench 48 the set plunger 17 and the connecting element 46 are drawn toward or moved away from each other whereby the set is adjusted to receive its proper movement from the 9am lever 41 to set the eyelet securely in the material. The set plun er and set are locked in their adjusted position by turning the lock nut between the nut and washer 47 so that the sides of the opening in the wrench 48 will engage the sides of the screw ihmg'e 45 and prevent the screw turn ng,

A slidable anvil 60, mounted in a guide 61 in the frame 1, is adapted to slidebclwcen the die 7 and the material, after a hole is punched in the material and the material is elevated, in the manner hereinafter described, and is provided with an opening 62 and a die 63 adapted to co-act with the punch and set in introducing the eyelet in the hole in the material and in setting the eyelet in the material, in the manner 'hereinafter more fully described. The anvil is actuated by a cam 65 in cam disk 66 mounted upon shaft 23 and cam arm 67 fulcrumed at 68' on the frame 1. Said arm is connected to the anvil by link 69. The cam arm 67 is provided with a cam roller 70 for engaging the cam 65 to eifect the operation of the anvil through the cam arm by the cam. The material, after a hole is punched therein, is positively lifted off the die 7 to permit the anvil 60 to slide between .the material and the die, by means of a lift for receiving the eyelet, and a spring dog 82, under the tension of ring 83 for engaging and maintaining t e eyelet in said recess, is adapted to feed the eyelet into a position where it receives the punch and is en gaged by the set to be introduced into the hole in the material and to be set in the ma terial. The feed bar 80 may also be provided with an engaging spring member 85 to engage the eyelet e'nd maintain it in its proper position on the feed bar to insure registration of the eyelet with the punch and set, when the eyelet is fed to the punch and set. A cam may be rovided on the frame 1 to be engaged by 9. ug 91 on the member -85 to raise the member sufliciently to permit the eyelet to pass under the member into the feed bar recess 81 from a chute to be described hereinafter. The feed bar 80' is operatively mounted in the guide Gland is ac tuated by cam 95 in cam disk 66 and cam arm 96 fulcrumed at 68. The cam arm 96 is provided with a cam roller 97 which engages the cam 95 and is connected to the feed'bax 80 by link 98 whereby the operation of the feed bar is effected by the cam through the cam arm.

The eyelets are delivered upon the feed bar 80 from a magazine 100, through a chute 101. The chute 101 is mounted upon a plate 102 secured'to the frame 1. The magazine is loosely mounted upon a shaft 103 jourv 'naled in bearing 104 on the plate 102. The

magazine is open at one end which end rests againstthe upper portion of the plate 102. The upper portion of the plate 102 is provided with a recess 105 which registers with the open end of the magazine and communicates with the upper end of the chute 101.

he side wall of the magazine is inclined so t at the eyelets will roll into the recess 105 in the plate 102. The eyelets are supplied to the magazine through .a hopperlOG. The shaft 103 is provided with an 'arm 107 which is connected to cam lever 25 by link 1025, whereby said shaft is oscillated by said lever. A,brush 110 mounted upozrtheshaft 103 within the recess 105 is oscillated with the shaft to sweep the eyelets into the upper end of the chute 101. The magazine 100-is,

locked to the shaft =103,-to oscillate therewith to agitate the e elets by means of a pin 111 on' arm 112 which is detachahly mounted on the end of said shaft outside of the closed end of the magazine, and holes 100 in said end of the magazine which e adapted to receive said pin. Said end of he shaft 103 is flattened and fits in a slot 113 in the arm 112 whereby-the arm is locked to the shaft so that the arm will oscillate with the shaft. The arm is held on the end of the shaft by means of a pin 11-1 fitting inthe end of the shaft. The magazine 100 isl rovided with a door 115 and may vbcmianua ly turned upon disengaging the pin 111 from the shaft 103 in which it rests, into such position that. the eyelets may he removed from the magazine, if desirable, through said door, upon open ing the door. A spring-dog 116 pivoted in thelower end of the chute 101 and under the tension ofs )ring 117 forms the lowermost; extremity o the forward side wall of the chute and is normally maintained in parallel alineinent with the main section of said wall by' its sprin 117 so that the eyelets normally will be guided into the recess 81 in thefeed bar 80 as they drop through the chute. A 'pulley120 mounted on shaft 23 is adapted to be belted to a source of 7 power, (not shown) for the purpose of driving the shaft 23. The pulley 120 may be rovided with any well known commercia clutch (not shown) to connect the pulley with the shaft 23, or to disconnect the pulley from the shaft so that the shaft may be driven to effect in termittent-ly the successive cycles of operations of the machine. Power, however, may

beiapplied to-the machine, to run the machine in any other snitable manner.

The operation of my lowst-The ,magazi'ne 100 being supplied with eyelets, power is applied to the pulley 120alnd the shaft 23 anicani disks 22 and (36 are rotated; the feed bar 80 is drawn rcarwardly by cam 95 through cam arm 96 and invention is as folj the connectionsbetween the bar andlever,

until the feed bar recess 81 registers with the lower extremity of the chute 101 to receive aneyelet, during which movement of the feed bar the dog 82 engages the dog 11G the brush into the chute; the eyelets drop down the chute one upon another, the fore.-

most eyelet dropping out of the lowermost end of the chute into the recessSl in the feed bar 80; the feed bar is then" pushed forward by the cam 95through cam arm 96 and link 98 untilthe eyelet rests inthe path of movement of the punch 14 and set 15, during which movement of the feed bar the dog 82 disengages the do 116 and engages the eyelet in the feed. ar recess 81 and maintains the eyelet in said recess, the lug 91 on the'engaging member 85 disengages the cam 90 and said member also engages the eyelet, insuring registration with the punch 14 and set- 15 and the side of the feed bar adjacent the chute closes the lower end of the chute and prevents the'eyelets dropping out of said end of the chute. When the feed bar is in its 'fo'rwardposition and the eyelet is in the path of movement of the punch 14 and set '15 and registers properlv therewith, the punch and set are in an eleyated position abovethee yelet, the anvil (i0 is in its rearward position away from the 'die. 7 and the lifting arm '72 isin its lower position. \Vhen/the feed bar, eyelet. punch, set, anvil and lifting arm are in the above described positions the material in which the eyelet is to be set, is placed upon the die 7 and lifting arm 72; the punch 11 is then forced downward, by the cam 21 through cam lever 25. link 29, stud 2S'and punch plunger 16, through the opening-in the evelet and impales the eyelet upon itself; the

operating means into its eyelet receiving position and the eyelet being impaled upon I the punch causes the dog 82 to swing on its pivot and release the'eyelet from the feed bar: as the downward movement of the punch continues the punch punches a hole in the material and ejects the punched out piece of material throughthe opening 8 'andpassage 9 in the die 7 a'mldieholder 5 re spectivelyrthe punch 13 then I110\0(l-11P\\' 211'd by its operating mechanism, and the'lifting arm 72 is eleyated, by means of cam 76 and cam arm 73 which movement ofthe liftin armelevates the material a sufficient dis: tance to retain the puneh in; the opening which it has punched in the material and to allow the anvil O0 to pass thereunder; the anvil 60 is then moved forward by cam 65 through cam arm (31' and link (39, over the (lie 7 until the anvil opening (32 registers with the die opening 8; the lifting arm 72 is then lowered level with the anvil and the punch ll forced downward through the openings (32 and S in the anvil and die 7 respectively during which m vements of the lifting arm and punch the material is lowered upon the anvil G0; the set 15 is then forced downward, by cam -10 through cam lever 41, link 4:, union 43 and set plunger 17, during which movement the set engages the eyelet and forces the shank thereof through the hole in the material, stripping i the material from the punch and transferring the materi '.l from the punch to the eyelet; the punch 14 and set 15 and the lifting arm T2 are then raised, by their respective operating cams, and the material and eyelet are raised'by'said lifting arm, into such positions that the punch and eyelet will be entirely out of the anvil opening 02 and with the eyelet still impaled on the punch; the anvil is then moved forward by its operating cam until the die (33 rests directly in the path of movement of the punch and set and registers withthe shank of the eyelet; the punch is then moved downward until its lower end rests centrally upon the die 63, to insure accurate registration of the eyelet with the die when the eyelet descends upon the die; the lifting arm 72 is then lowered level with the anvil and the set is forced downward against theliead of the eyelet. and the shank of the eyelet is thereby driven against the die 63 and clenched by the die against the under side of the material, thus setting the eyelet in the material. The punch and set are then withdrawn from the eyelet and the material, the

punch being withdrawn in advance of the set to strip the eyelet a'ndmaterial from eyelet set itself and'the material withthe therein is removed. 4

The liftin arm 72, while it afiords a positive means for lifting the material, after it is punched, over the anvil 60 is not an indispensable means for accomplishing this operatiomnnder ordinary conditions, inasmuch asthe material, under such conditions, adheres to the punch after it punches the material and is lifted by the punch. However. the 'material is liable to-slip on the punch and fail to be elevated above the anvil by the punch especially if the material is heavy, in which event the machine would have to be stopped and the material adj listed by hand, thus impairin the eliiciency v of the machine, were it not or the lifting arm which insures the lifting of the ma-.

terial.

' In case an eyelet should fail properly to enter the recess 810i the feed bar 80, said eyelet will be engaged by the feed-bar and T ot alinement wit 1 the forward side wall of the chute passageway, and permit the eyelet to escape. thus avoiding choking of the chute and interference with the operation of thceyelet feed bar.
